Actually DEP and the hardware introduced with 64-bit CPUs does work and
is supported by 32-bit versions of Windows.

The instructions being used are all 32-bit and so the 64-bit power of
your CPU doesn't get utilised, but the bit used for DEP is still in use
so definitely any version of Windows XP (and other current Windows
versions, perhaps?) will show the DEP options.

For older hardware it is OFF, for newer hardware it is ON by default, but
can be altered to cover more applications then just the essential
Windows components.

64-bit instructions and performance are a whole other section.
